McPherson - Model 209V -Vacuum Compatible High Resolution Czerny-Turner Monochromator
FromMcPherson
This instrument offers all of our great features and options: a wide variety of patented SNAP IN diffraction gratings, efficient broadband reflective coatings, and master polished optics. McPherson Czerny-Turner instruments with focal lengths greater than 0.67-meters allow you to use larger 120-mm x 140-mm grating or a 110-mm x 110-mm grating. The large grating offers almost 40% more area, achieving a faster f/number, and more throughput. In these models the grating can also rotate through an auxiliary 20° for extension of wavelength range. For the 1200-g/mm grating the high wavelength changes from 1300-nm to 1575-nm (more than 20% extra wavelength coverage!).
